INBACSAM064O000 – Samsung VRF to BACnet IP/MSTP gateway with support for up to 64 indoor units

INBACSAM064O000 – Samsung VRF to BACnet IP/MSTP gateway with support for up to 64 indoor units. 

The newer version of this device is IN770AIR00MO000

The INBACSAM064O000 IntesisBox Gateway has been designed to ensure seamless and bidirectional communication between Samsung NASA VRF systems and BACnet IP or BACnet MS/TP-based building automation networks. This powerful integration tool allows full control and monitoring of up to 64 indoor units from any BMS, SCADA, PLC, or BACnet-compatible master device.

The gateway connects directly to the communication bus of the Samsung outdoor unit, enabling efficient and real-time access to essential air conditioning parameters. Users can manage operating modes, fan speeds, temperature setpoints, and also retrieve alarm data and internal diagnostics from outdoor units—enhancing serviceability and system transparency.

Configuration is made easy with the Intesis MAPS software. It allows for flexible configuration, mapping, and diagnostics through a graphical interface. The scan function automatically detects all indoor units connected to the system, significantly reducing setup time. In addition, the software includes powerful diagnostic tools for fast fault identification, saving time during commissioning and maintenance.

The INBACSAM064O000 is an ideal solution for integrating Samsung VRF systems into commercial automation environments such as hotels, shopping centers, and office buildings. It is compatible with both IP and serial BACnet networks, offering maximum installation flexibility. Its compact plastic housing, DIN rail compatibility, and broad power input range simplify deployment.
